Abstract: ABSTRACT OF THE DISCLOSURE            A self watering planter having a base divided into two compartments, one for soil and one for water, separated by a divider wall.  A wick extends from the water compartment over the divider wall into the soil compartment.  A common upper rim encircles both compartments and a cover which defines a single compart-ment is seated on the rim, so that the cover forms with the base an enclosed space communicating with both lower compartments.  Thus evaporation from either lower compart-ment is recycled.  The lower surface of the cover top wall can be dimpled to distribute condensate more evenly over the plants.

Abstract: APPLICATION FOR CANADIAN PATENT                        SPECIFICATION     ABSTRACT OF THE DISCLOSURE      A numerically controlled machining center has a tool magazine, automatic tool changer, workpiece shuttle, and a workpiece magazine which holds enough workpieces for operation by the machining center for an entire shift of approximately eight hours.   The numerical controls are programmed to perform predetermined machining opera-tions on each workpiece, in turn, and to replace each finished work-piece with a fresh workpiece at the end of each machining program.          A proximity switch is mounted on the machining center for checking tools to detect broken or incorrect tools.  The tools are positioned adjacent to the proximity switch and are rotated while the output of the proximity switch is counted for one complete rotation of the tool to determine the number of radially extending teeth on the tool.     If the tool has too few or too many teeth, thus indicating a broken or incorrect tool, it is replaced by another tool of the same type.          If no alternate tool is available in the tool magazine, the machin-ing cycle is automatically suspended.

Abstract: SAILING BOAT AND METHOD OF OPERATING THE SAME                   Abstract of the Disclosure A sailboat having a hull, a sail assembly and a keel.  The keel is shaped as a longitudinally and horizon-tally extending hydrofoil which develops a vertically downward force.  When the boat is traveling in a heeled position, the keel member exerts a downwardly and outwardly directed keel force having a lateral force component to substantially counteract an opposite lateral aerodynamic force component exerted by wind against the sail assembly, thus diminishing the yaw angle in the travel of the boat.          Further, the keel force acts through the center of gravity of the boat to produce a righting moment which tends to counteract the capsizing moment developed by the force of the wind against the sail assembly.

Abstract: RECEIVE/BYPASS CIRCUIT FOR SUBSYSTEMS                     IN POLLING SYSTEM                             Abstract A polling system includes a central processor and a plurality of subsystems connected in a loop to the central processor.  A receive/bypass circuit in each subsystem includes a depletion mode field effect transistor having its drain and source electrodes connected in series in a bypass line at the subsystem. A control circuit is connected to a polling signal input line at each subsystem.  When the subsystem has power, the control circuit routes the polling signal to a terminal device in the subsystem while estab-lishing a conduction-inhibiting voltage at the gate electrode of the field effect transistor.  When the subsystem is unpowered or out of service, a switching transistor in the control circuit isolates the terminal device from the polling signal input line. The polling signal bypasses an unpowered subsystem through the unbiased field effect transistor in the bypass line.

Abstract: ABSTRACT A differential capacitive force responsive transducer provides a substantially linear relationship between transducer output and input varia-tions.  A pressure or load to be measured is applied to one surface of a deflectable diaphragm, the opposite surface of which includes at least a pair of electrodes at different positions, such that when the diaphragm flexes there is a differential deflection of the electrodes.  A substantially rigid electrode-bearing plate is secured to the electrode-bearing face of the dia-phragm by a spacer or spacers in an intermediate flexure region of the dia-phragm, to define separate capacitive elements with the diaphragm electrodes. The plate thus moves with the diaphragm, maintaining a fixed spacing at the spacer elements, but with the spacings between the elements varying in op-posite senses.  With this construction, the transducer can be of low cost, small size, precision manufacture, and use readily deposited thick or thin film electrodes.  Moreover the circuits may automatically be adjusted to pro-vide selected nominal zero and range values, so that the transducer can be utilized interchangeably with other transducers in mass production systems. Furthermore, the differential capacitance values obtained from a single trans-ducer directly provide digital values to a processor, by oppositely varying two variable frequency oscillators.  The difference between these frequencies is generated and can be sampled to generate pulse counts during successive time intervals.

Abstract: ABSTRACT OF THE DISCLOSURE         A conduit is apertured through the wall thereof and 3 hollow stem, e.g., for sprinkler heads and the like, is provided with a bulbous base, and a double sloping shouldered base with the diameter of the bulbous base being slightly less than the diameter of the conduit aperture so that the lower end of the hollow stem is insertable through the aperture.  A malleably deformable, e.g., resilient, has an outside diameter just slightly smaller than the diameter of the aperture in the conduit enabling snug insertion of the sleeve through the aperture, and an internal diameter enabling snug passage of a hollow stem therethrough, the sleeve including an internal chamfered upper end and an external chamfered lower end, the length of the sleeve being greater than the  thickness of the conduit.   A hollow stem includes a bulbous base, the bulbous base being of a larger diameter than the external diameter of the hollow stem but being of a slightly less diameter than the diameter of the aperture, the base including a first shoulder at the lower end thereof, the first shoulder sloping upwardly and inwardly towards the portion of the stem which is disposed thereabove, and a second frusto-conical shoulder formed thereon spaced above the first frusto-conical shoulder, the second frusto-conical shoulder sloping inwardly and upwardly toward an upper cylindrical stem portion, the diameter of the upper stem portion being less than the diameter of the stem between the second frusto-conical shoulder and the first frusto-conical shoulder, a portion of the stem immediately above the second shoulder being screw threaded. Clamping means are associated with the hollow stem, the clamping means comprising a screw-threaded cylindrical coupling engageable with the portion of the stem above the frusto-conical base which is screw-threaded, the external diameter of the lower end of the cylindrical coupling being greater than the diameter of the aperture, wherein, when the hollow stem and the sleeve are inserted into the aperture, and when the clamping means are actuated to apply a longitudinal upward force against the base of the sleeve, initial actuation of the clamping means forces the lower end of the sleeve over the second frusto-conical shoulder and down to the frusto-conical base, and the sleeve is expanded radially outwardly into sealing engagement with the wall of the aperture.          Further tightening expands the sleeve by the frusto-conical base which cannot pass through the aperture because of the thickness of the resilient sleeve.  When tightened fully, the hollow stem is held in firm sealing relationship with the aperture through the wall of the conduit.
